This invention aims to provide novel means whereby a stench proceedlngfrom a drler may be done away Wltll, especial reference being had todrlers in which blood,

'tankage, fish meal, grain, and the like, are

handled. The invention aims to provide a deodorizer of novelconstruction, and to provide novel means for supplying fluid pressure tothe conduit that carries the vapors and the like from the drier to thedeodorizer.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that sort to which the presentinvention appertains.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes may be made inthe precise embodiment of what is shown by the invention hereindisclosed, within the scope of what is claimed, without departing fromthe spirit of the invention.

In the accompanying drawings:

Figure 1 shows in elevation, a device constructed in accordance with theinvention;

Figure 2 is a: longitudinal section through the deodorizer;

Figure 3 is a transverse section through the drier;

Figure 4 is a fragmental section on the line 44 of Figure l;

Figure 5 is a fragmental longitudinal section of one of the nozzles.

The numeral 1 designates a drier of the kind used for drying grain,blood, fish meal, tankage, and the like. The drier 1 includes areceptacle 2 about which is located a shell 3, the space between theshell 3 and the receptacle 2 constituting a steam jacket 4. The shell 3is supplied with a steam inlet pipe 5 discharging into the steam jacket4.

A shaft drier 1 and carries a rotatable agitator 7 which may comprisepaddles. The numeral 8 designates a conduit leading from the receptacle,at the top thereof, to the deodorizer 20, which will be describedhereinafter.

6 is journaled for rotation in the 1929. Serial No. 378,513.

The conduit 8 may be made, for the most part, out of stockmaterials. Thepart 10 ofthe conduit 8 which is immediately adjacent to the drier 1 issomewhat greater in diameterthan the'part 11 which is adjacent to thedeodorizer 20. At the place where the parts 10 and 11 of the conduit 8are joined together, there is a reduced throat 12, shown in Figure 4.The numeral 14 designates a fluid pressurepipe which may carry steamfrom any desired source, compressed air, etc.

embodiment of the invention,

In the present however, the lower end of the fluid pressure pipe 14communicates with the steam jacket 4 of the drier 1. At its upper end,the steam pressure pipe 14 has a nozzle 15 located in the part 10 of theconduit 8 and discharging into the throat 12. A strainer 16 is locatedin the. pipe 14. In the pipe 14 is dis posed a valve 17 which is underthe control of an operator. The part 11 of the conduit 8 is connected toone end of a T 9, the vertical branc' of the T 9 being connected to thetapered upper end 18 of the cylindrical body 19 of the deodorizer 20. Onthe outer end of the horizontal branch of the T 9 there is a detachablecap 25, which may be removed to permit an operator to get at the conduit8 and clean it out. 7

j The body 19 of the deodorizer 20 has a ta pered lower end 21discharging through a trap 23 into a pipe 24 which may lead to a sewer(not shown). The deodorizer 20 is supported on longitudinally adjustablelegs 22 The numeral26 designates a water supply pipe in which isinterposed a valve 27 under the control of an operator. A strainer 28 islocated in the pipe 26. The pipe 26 extends downwardly through thevertical branch of the T 9, into the body 19 of the deodorizer 20. Thelower end of the pipe 26 is connected to a tubular nozzle 29, the lowerend of which is closedby a cap 30. The nozzle 29 may be located at theaxis of the body 19 and the deodorizer 20. The nozzle 29 is providedwith openings 31 arranged in longitudinal lines, as shown in Figure 2;penings are staggered around the nozzle 29, as Figure 5 will show. Theopenings 31 in the norzle 29 slant downwardly and outwardly, as can beseen in Figure 5.

The cap 25 can be removed, and then the nozzle 15 and the throat 12 ofFigure 4; will facilitate the cleaning of the conduit.

In practical operation, the material to be dried is placed in thereceptacle 2 of the drier. The steam in the jacket a has a pressure offrom forty pounds to eighty pounds to the square inch with a temperatureof 220 F. up, and the moisture in the material in the drier is drivenoff, the moisture running from 30 to 80 percent by weight. The agitator7, of course, lreeps the material in the drier stirred up whilst thedrying operation is going on. When the moisture becomes hot enough, itrises in the drier and goes over through the conduit 8, the passage ofthe vapor through the conduit 8 being accelerated because fluid pressureis discharged from the nozzle 15 into the throat 12, the pressure fluid,in the present eml odiment of the inven tion, being steam from the steamjacket 4 of the drier. ater from the pipe 26 flows outwardly through theholes 31 in the nozzle 29 and is discharged into the body 19 of thedeodorizer 20, the vapors entering the deodorizer by way of the T 9. Thewater discharged from the nozzle 29 absorbs the moisture that thedeodorizer has received from the conduit 9 and the waste water runs awaythrough the trap 28 and the pipe 24 to a sewer (not shown).

The construction is such that the ranksmelling vapor proceeding from thedrier is taken care of, there being no objectionable odor in and aboutthe entire apparatus. The device is simple in construction and may bemanufactured at a small cost.

Having thus described the invention, what is claimed is:

In a device of the class described, a deodorizer comprising a tubularbody having an outlet, a T connected to the top of the body and havingoppositely disposed branches, one of which is connected to a source ofgas to be deodorized, a water supply pipe and a nozzle extended downthrough the T, the nozzle discharging into the body, a conduit connectedto said one of said oppositely disposed branches of the T, a removablecap on the other of said oppositely disposed branches of the T, areduced throat in the conduit, and a fluid pressure pipe entering theconduit and discharging through the throat directly toward the removablecap, the throat and the fluid pressure pipe acceleratingthe flow of gasto be deodorized, when the cap is in place, and facilitating a cleanofthe conduit when the cap is removed.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature.

ARTHUR WHEELER PELPHREY.
